  • Thread-topic: [Xen-devel] [PATCH v1 01/02] HVM firmware passthrough libxl support

This patch introduces support for two new parameters in libxl:

smbios_firmware=<path_to_smbios_structures_file>
acpi_firmware=<path_to_acpi_tables_file>

The changes are primarily in the domain building code where the firmware files
are read and passed to libxc for loading into the new guest. After the domain
building call to libxc, the addresses for the loaded blobs are returned and
written to xenstore.

Additionally, this patch switches to using the new xc_hvm_build() routine.
